Electric Car Proposal
PROBLEM
With its electricity power it is less harmful for atmosphere.
I used electrical car because its less harmful for atmosphere DO NOT REPEAT YOURSELF
PRIOR ART
GAP
I want my car to run with electrical power
OBJECTIVE
.
electrical car
benefit for trafic.
DESIRED FUNCTIONS
sportive
performance
cheaperlightweighted
more free space
high energy density batteries
less likely than most to lose their charge when not being used
charging time will be 2 hours and it will go 12 hours with that 2 hours charging
if any electrical error occured to not to give the engine harm.
the regulator,engine,battery box SHOULDn’t heat up
park it easier
DESIGN CRITERIA
I need to put a nice????? performance engine which Works with electricity.
I need to put a regulator because electric engine takes its power from regulator.
And regulator takes its energy from rechargable battery.
lightweighted and free space : cables instead of pipes.
And I will place auto secure system that will close the engine
The cooling system
smaller
Material Selection:
..
Its only disadvantage is electrical engine will be expensive because of its hardware.
I will use Lithium-ion batteries. Which have a very.I will use 50kW regulator it takes
300volt DC and creates 3x240 AC.
The car will take 50 batteries WEIGHT???
and its.
I can use asid SPELLING bateries instead they are cheaper
but Li-ion batteries’s duration is better and they can be recharged.
Method:
I will put a regulator near electric engine and cables to reach batteries to gain
electricty from them.Also
I will place cooling system under the regulator and the battery box.
PERFORMANCE TESTS: DESCRIBE TESTS
Test Results:
With Li-ion batteries our car is going more range without any problem.
The batteries can be charged easiliy at 2 hours.
The cooling system Works well
the regulator,engine,battery box isn’t heating up.
And our car is smaller to park it easier.
It is also eco-friendly.
Scientific Experimen
PROBLEM
Colon cancer
LIT SEARCH
It also reduces crohn and colit change which are a reason for colon cancer.
YOU CANNOT MAKE THAT STATEMENT. IT IS THE HYPOTHESIS YOU SHOULD BE
TESTING!!!
GAP ????
HYPOTHESIS Shalgam reduces the risk of colon cancer
MECHANISM: because it removes the harmfull things WHAT THINGS ???from blood.
We have different groups.
1. Group has colon cancer risk from their family because its genetical.They drink
shalgam.
2. Group has colon cancer risk from their family too but they won’t drink shalgam.
3. .
We tried each group with 100 people.
We calculated being cancer changes of that groups and we see;
1st group have % 30
2nd group have % 40
And we see here the same type people drink shalgam have lower chance of being
cancer.
CONCLUSIONS
And we obtained result that shalgam reduces the chance of being colon cancer.
